Let *[tex \Large x] represent the number of quarters.  Then *[tex \Large 20\ -\ x] must be the number of dimes.  The value of the quarters is *[tex \Large 25x] cents, and the value of the dimes is *[tex \Large 10(20\ -\ x)], and the sum of these two values must be the total amount of money, $3.65, which is to say 365 cents so as to express everything in the same units.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 25x\ +\ 10(20\ -\ x)\ =\ 365]


Just solve for *[tex \Large x]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
